Before reciting this Śrīmad-Bhāgavatam, which is the very means of conquest, one should offer respectful obeisances unto the Personality of Godhead, Nārāyaṇa, unto Nara-nārāyaṇa Ṛṣi, the supermost human being, unto mother Sarasvatī, the goddess of learning, and unto Śrīla Vyāsadeva, the author.
(Srimad Bhagavatam-----1:2:4-----purport).

That Nara-Nārāyaṇa Ṛṣi, who is a partial expansion of Kṛṣṇa, has now appeared in the dynasties of Yadu and Kuru, in the forms of Kṛṣṇa and Arjuna respectively, to mitigate the burden of the world.
Nārāyaṇa is the Supreme Personality of Godhead, and Nara is a part of the Supreme Personality of Godhead, Nārāyaṇa. Thus the energy and the energetic together are the Supreme Personality of Godhead. Maitreya informed Vidura that Nara, the portion of Nārāyaṇa, had appeared in the family of the Kurus and that Nārāyaṇa, the plenary expansion of Kṛṣṇa, had come as Kṛṣṇa, the Supreme Personality of Godhead, with the purpose of delivering suffering humanity from the pangs of material burdens. In other words, Nārāyaṇa Ṛṣi was now present in the world in the forms of Kṛṣṇa and Arjuna.
(Srimad Bhagavatam-----4:1:59-----translation and purport).

Let me offer my respectful obeisances unto Nara-Nārāyaṇa, the best of all saintly persons, the Supreme Personality of Godhead. He is the most self-controlled and self-realized, He is free from false prestige, and He is the asset of persons who have no material possessions. He is the spiritual master of all paramahaṁsas, who are the most exalted human beings, and He is the master of the self-realized. Let me offer my repeated obeisances at His lotus feet.
(Srimad Bhagavatam-----5:19:11-----translation).

Badarikāśrama in the Himalayas, the abode of the Nara-Nārāyaṇa sages, is a great place of pilgrimage for the Hindus. Even up to the present, hundreds and thousands of pious Hindus go to pay respects to the incarnation of Godhead Nara-Nārāyaṇa. It appears that even five thousand years ago this holy place was being visited by such a holy being as Uddhava, and even at that time the place was known to be very, very old. This particular pilgrimage site is very difficult to visit for ordinary men because of its difficult situation in the Himalayas in a place which is covered by ice almost all year. A few months during the summer season people can visit this place at great personal inconvenience. There are four dhāmas, or kingdoms of God, which represent the planets of the spiritual sky, which consists of the brahmajyoti and the Vaikuṇṭhas. These are Badarikāśrama, Rameśvara, Jagannātha Purī and Dvārakā. Faithful Hindus still visit all these holy places for perfection of spiritual realization, following in the footsteps of devotees like Uddhava.
(Srimad Bhagavatam-----3:4:22-----purport).

Uddhava was considered to be the best amongst all devotees of that time, and therefore he was directly instructed by the Lord's grace, so that people might take advantage of Uddhava's knowledge after the disappearance of the Lord from the vision of the world. This is one of the reasons why Uddhava was advised to go to Badarikāśrama, where the Lord is personally represented by the Nara-Nārāyaṇa Deity. One who is transcendentally advanced can gain direct inspiration from the temple Deity, and thus a devotee of the Lord always takes shelter of a recognized temple of the Lord in order to make tangible advancement in transcendental knowledge by the grace of the Lord.
(Srimad Bhagavatam-----3:4:30-----purport).

In the heavenly planets, bands began to play, and they showered flowers from the sky. The pacified sages chanted Vedic prayers, the denizens of heaven known as the Gandharvas and Kinnaras sang, the beautiful damsels of the heavenly planets danced, and in this way, at the time of the appearance of Nara-Nārāyaṇa, all signs of good fortune were visible. Just at that time, great demigods like Brahmā also offered their respectful prayers.
(Srimad Bhagavatam-----4:1:54-55-----translation).

The demigods said: Let us offer our respectful obeisances unto the transcendental Personality of Godhead, who created as His external energy this cosmic manifestation, which is situated in Him as the air and clouds are situated in space, and who has now appeared in the form of Nara-Nārāyaṇa Ṛṣi in the house of Dharma.
(Srimad Bhagavatam-----4:1:54-56-----translation).

(Maitreya said:) O Vidura, thus the demigods worshiped with prayers the Supreme Personality of Godhead appearing as the sage Nara-Nārāyaṇa. The Lord glanced upon them with mercy and then departed for Gandhamādana Hill.
(Srimad Bhagavatam-----4:1:54-58-----translation).

(Śukadeva Gosvāmī continued:) The glories of the Supreme Personality of Godhead are inconceivable. He has appeared in the form of Nara-Nārāyaṇa in the land of Bhārata-varṣa, at the place known as Badarikāśrama, to favor His devotees by teaching them religion, knowledge, renunciation, spiritual power, sense control and freedom from false ego. He is advanced in the opulence of spiritual assets, and He engages in executing austerity until the end of this millennium. This is the process of self-realization.
(Srimad Bhagavatam-----5:19:9-----translation).

Nārada, the most powerful saintly sage, also worships Nara-Nārāyaṇa by chanting the following mantra: The Supreme Personality of Godhead is the master of the creation, maintenance and annihilation of this visible cosmic manifestation, yet He is completely free from false prestige. Although to the foolish He appears to have accepted a material body like us, He is unaffected by bodily tribulations like hunger, thirst and fatigue. Although He is the witness who sees everything, His senses are unpolluted by the objects He sees. Let me offer my respectful obeisances unto that unattached, pure witness of the world, the Supreme Soul, the Personality of Godhead.
(Srimad Bhagavatam-----5:19:12-----translation).

Once when Nārada, the great devotee and ascetic amongst the demigods, was traveling among different planets, he desired to meet the ascetic Nārāyaṇa personally in Badarīkāśrama and offer Him respects. This great sage incarnation of Godhead, Nārāyaṇa Ṛṣi, has been undergoing great penances and austerities from the very beginning of the creation to teach the inhabitants of Bhārata-varṣa how to attain the highest perfectional stage of going back to Godhead. His austerities and penances are exemplary practices for the human being. The incarnation of God Nārāyaṇa Ṛṣi was sitting amongst many devotees in the village known as Kalāpa-grāma. Of course, these were not ordinary sages sitting with Him, and the great sage Nārada also appeared there. After offering his respects to Nārāyaṇa Ṛṣi, Nārada asked Him exactly the same question King Parīkṣit asked Śukadeva Gosvāmī. Then the Ṛṣi answered by following in the footsteps of His predecessors. He narrated a story of how the same question had been discussed on the planet known as Janaloka, which is above the Svargaloka planets, such as the moon and Venus. On this planet, great sages and saintly persons live, and they once discussed the same point regarding the understanding of Brahman and His real identity.
(Krsna Book).

Thus the Veda-stuti, or the prayers offered by the personified Vedas to Garbhodakaśāyī Viṣṇu, were first narrated in disciplic succession by Sanandana to his brothers, all of whom were born of Brahmā at the beginning of the universe. The four Kumāras were the first-born sons of Brahmā; therefore they are known as pūrva-jāta. It is stated in the Bhagavad-gītā that the paramparā system, or the disciplic succession, begins with Kṛṣṇa Himself. Similarly, here, in the prayers of the personified Vedas, it is to be understood that the paramparā system begins with the Personality of Godhead Nārāyaṇa Ṛṣi. We should remember that this Veda-stuti is narrated by Kumāra Sanandana, and the narration is repeated by Nārāyaṇa Ṛṣi in Badarīkāśrama. Nārāyaṇa Ṛṣi is the incarnation of Kṛṣṇa for showing us the path of self-realization by undergoing severe austerities. In this age Lord Caitanya demonstrated the path of pure devotional service by putting Himself in the role of a pure devotee. Similarly, in the past Lord Nārāyaṇa Ṛṣi was an incarnation of Kṛṣṇa who performed severe austerities in the Himalayan ranges. Śrī Nārada Muni was hearing from Him. So in the statement given by Nārāyaṇa Ṛṣi to Nārada Muni, as narrated by Kumāra Sanandana in the form of the Veda-stuti, it is understood that God is the one supreme and that all others are His servants.
(Krsna Book).

In the Caitanya-caritāmṛta it is stated, ekale īśvara kṛṣṇa: (CC.1:5:142) "Kṛṣṇa is the only Supreme God." Āra saba bhṛtya: "All others are His servants." Yāre yaiche nācāya, se taiche kare nṛtya: "The Supreme Lord, as He desires, is engaging all the living entities in different activities, and thus they exhibit their different talents and tendencies." This Veda-stuti is thus the original instruction regarding the relationship existing between the living entity and the Supreme Personality of Godhead. The highest platform of realization for the living entity is the attainment of devotional life. One cannot be engaged in devotional life, or Kṛṣṇa consciousness, unless one is fully free from material contamination. Nārāyaṇa Ṛṣiinformed Nārada Muni that the essence of all the Vedas and Vedic scriptures (namely, the four Vedas, the Upaniṣads, the Purāṇas and the Vedānta-sūtra) is to render transcendental loving service to the Lord. In this connection Nārāyaṇa Ṛṣi has used one particular word—rasa. In devotional service this rasa is the via medium or the basic principle for the exchange of dealings between the Lord and the living entity. Rasa is also described in the Vedas: raso vai saḥ. "The Supreme Lord is the reservoir of all pleasure." All the Vedic scriptures, including the Purāṇas, the Vedas, the Upaniṣads and the Vedānta-sūtra, teach the living entities how to attain the stage of rasa. The Bhāgavatam also says that the statements in the Mahā-Purāṇa (Śrīmad-Bhāgavatam) constitute the essence (rasa) of all Vedic literature. Nigama-kalpa-taror galitaṁ phalam: (S.B.1:1:3) the Bhāgavatam is the essence of the ripened fruit of the tree of the Vedic literature.
(Krsna Book).

One who can remember everything perpetually is called a śruti-dhara. A śruti-dhara brahmacārī can repeat verbatim all that he has heard, without notes and without reference to books. The great sage Nārada has this qualification, and therefore, having taken instructions from Nārāyaṇa Ṛṣi, he is engaged in propagating the philosophy of devotional service all over the world. Because such great sages can remember everything, they are thoughtful, self-realized and completely fixed in the service of the Lord.
Thus the great sage Nārada, after hearing from his spiritual master Nārāyaṇa Ṛṣi, became completely realized. He became established in the truth, and he became so happy that he offered prayers to Nārāyaṇa Ṛṣi. Nārada Muni addressed Nārāyaṇa Ṛṣi as an incarnation of Kṛṣṇa and specifically addressed Him as the supreme well-wisher of the conditioned souls. It is stated in the Bhagavad-gītā that Lord Kṛṣṇa descends in every millennium just to give protection to His devotees and to annihilate the nondevotees. Nārāyaṇa Ṛṣi, being an incarnation of Kṛṣṇa, is also addressed as the well-wisher of the conditioned souls. As stated in the Bhagavad-gītā, everyone should know that there is no well-wisher like Kṛṣṇa. Everyone should understand that Lord Kṛṣṇa is the supreme well-wisher of everyone and should take shelter of Him. In this way one can become completely confident and satisfied, knowing that he has someone who is able to give him all protection.
(Krsna Book).

It is said that Arjuna is an empowered incarnation of Nara-Nārāyaṇa. He is even sometimes called Nara-Nārāyaṇa. The Nara-Nārāyaṇa incarnation is also one of Lord Viṣṇu's plenary expansions. Therefore, when Kṛṣṇa and Arjuna went to see Lord Viṣṇu, it is to be understood that Arjuna visited in His Nara-Nārāyaṇa capacity, just as Kṛṣṇa, when He displayed His pastimes in Dvārakā, acted in His Vāsudeva capacity.
(Krsna Book).

I offer my respectful obeisances unto You, who are the original Personality of Godhead, the witness in everyone's heart, and the incarnation of Nara-Nārāyaṇa Ṛṣi in the form of a human being. O Personality of Godhead, I offer my respectful obeisances unto You.
(Srimad Bhagavatam-----8:16:34-----translation).

Obeisances to You, the Supreme Personality of Godhead, Lord Kṛṣṇa, whose intelligence is ever unrestricted. Obeisances to the sage Nara-Nārāyaṇa, who always undergoes austerities in perfect peace.
(Srimad Bhagavatam-----10:86:35-----translation).

"Obeisances to You, O Supreme Lord Vāsudeva, and to Your forms of Saṅkarṣaṇa, Pradyumna and Aniruddha. O Supreme Personality of Godhead, all obeisances unto You. O Lord Nārāyaṇa Ṛṣi, O creator of the universe, best of personalities, master of this cosmos and original form of the universe, O Supersoul of all created entities, all homage unto You."
(Srimad Bhagavatam-----11:5:29-30-----translation).
